At 42:43 we actually can Be fooled By The Fact That There are 6 nodes and if Search Sin(nπ)=0 For L=0.25 we can Get A node but it's not a guarantee that it's the length between two end Nodes It can Actually also be Possible to become length between any two Nodes On The String . That's why I suggest to Compare The eqn with Standing wave Eqn to check for Wavenumber constant K and Further apply k=2π/lambda and reach at For 5th harmonic or 4th overtone Length = 5× Lambda/2, And There You Can Get Correct Verification . Although in both cases Length of String Comes Out To be 0.25m.
☝☝Sir mujhe ek doubt hai.. Last question me jo metre inverse aur t inverse tha voh kya hai???? t inverse bola hai toh direct frequency nahi ho jayegi???

Last question me me Length nikalne ke liye agar lambda ki value 2π/k se Nikal le kyuki k=62.8 Diya Hain phir....total nodes ban rahe Hain 6 so (5*lambda)/2 =length Isse length Nikal len to vo bhi same aayega 0.25 ke .. !!!😁💗💗💗💗💗

at 47:20 I tried calculating frequency by using the formula f = w/(2*pi) = 628/(2*3.14) = 628 / 6.28 = 100Hz.....but sir has got the answer as 20 Hz....i am confused as to which is correct...please confirm anybody....Thank you so much alakh sir for the wonderful video...my best wishes for you... :) :) :)

Kyonki aapne jo frequency nikali hai woh 5TH HARMONICS FREQUENCY hai.. aur question me FUNDAMENTAL/FIRST HARMONICS FREQUENCY puchi hai.. aap ek kaam kare.. 5×f1=f5 kare.. toh f1=20hz aa jaega
sir last ques me k ki valu 62.8 di he , k ko 2pie/lamda ko 62.8 ke equal kare to usse lamda ki valu aaegi 1/10 fir usse f=v/lamda me put karenge to f 100hz aaega.

Thank you sir with all my heart I watched all your lecture on waves and they are just amazing Too easy to understand However i watched it in 2x Thank you very much
Thank you so much sir...i was going in depression because you was not telling according to my course (from pakistan)..and there is not any good content of education channel which i prepare in lockdown... but there are few topics like wave matching with my course..I am really weak in that topic..thank you so much sir....love from pakistan❤💕💓🥰
From last question the equation is y=0.01sin(62.8/m x) cos(628/s t) If we compare with y=Asinkx coswt. Then W=628/s but w=2πf then from this then f should be 100hz but not why??? Someone explain

just wanna tell 47:03 sir took lamda=2l whereas it will come lamda=2l/5 and then you will get answer 100Hz..✅
aree actually fundamental frequency pucha hai na isiliye sir ne 2l liya
Thanks for helping all Students 🙏🙏
You are the Greatest Teacher 🤓🤓🤓
Alakh Pandey sir .
Really I have no words to say .... You teach in an impressive way ........ It help me a lot .
Thanks sir .👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Sir last question me 5th hormonic frequency=5/2l ×v
=5/2×0.25 ×10
=100HZ hi hogi
Sista in this question the fundamental frequency... Is asked... Not other harmonic frequency...
Oo I had same doubt thanks
Good m searching for your comment
Sir your teaching style is very nice😍😍
Thankyou soo much sir ....watching your videos at the end of my 11th to gain some confidence . You are providing us with quality education at free . Thankyou sir ❤️
Sir at Q at 23:47, if string are massless then u=0,then frequency will become infinite
❤❤ hats off sir aapke efforts ko. Ly
i will give neet this year physics sara aapke nam hai thankyou sir
Thank you... Soo much Sir... You are the Best 😊😊
sir aapne mere saare concepts clear kar diye iske liye bahut bahut shukriya
Sir mujhse waves keep aache questions nahi ban rahe hai please aap ek questions or video baba dijeye na please
Ok will try
@@PhysicsWallah sir plz karvado
Sir in last question plz reply
lambda = 2 pi by k
Lambda =0.1m
L=lambdaby 2
L=0.05
f = v by 2l
f = 100 hz
Thanks a lot sir may god bless you
Sir Aaj Maine Kota ke notes or apke lectures milaye ditto same to same,ab ander se confident Baad Gaya hai thankyou sir
Anyone thought sir left hand glove(black) is missing
Gloves summer me pehna jata hai n
@@PhysicsWallah 😀😀😀
@@PhysicsWallah sir kya bol rahe ho ? 😂
@@PhysicsWallah 😂
@@PhysicsWallah Sir aapke hath kharab ho skte h ...... plz gloves pehne kro
Ab sir ki videos pae sir ki khud ki ads aarahi hai
Its a proud momment for pwians
Hit like who feels that their string waves chapter is no more troubling after this series..
I feel so. Sir ke liye dil se izzat
Love you sir ....
Thankyou Thankyou sir for this amayyyyzing lecture!!!!! Loved it!!!!!! Thankyou Thankyou sir❤❤❤❤🙏🏻🙏🏻🙏🏻🙏🏻🔥🔥🔥🔥
Thank you sir for your support and motivation 😊🙏🙏🙏🙏
Sir aapka starting mujhe bht aacha lgata hai
Ur lectures are awesome I really love them but they r so lengthy
In last question part d we can't take Lambda=2L, because its the fifth fundamental
Sir you are a real hero
Sir...Bht acche se samjh aa gaya ....thank u sir😊
Hi pooja neet ki preparation kr rhi yaa iit ki
2 saal pehle wale bacche lucky thhe. Unhe aap se ❤️ mila
2 year ago wale comments ke beech tumhara 2 weeks ago wala comment dekh kr khusi hui😋😂
Sir you are hard, gjb pdhate ho jldi smj aata hai aur Dhanyawad hme gyan dene ke liye aur ek like kr dena plzz
Thank u sir for all of your hard work and dedication towards us
Sir please complete this chapter fast.Your teaching is great.Thanks a lot for all these.
Thank you for this lecture.😊
May God bless you😊
47:15 .... Sir f1 will be 100Hz optn D is also correct 💯 😊😊😊 Love from a MSC physics passout student 😅😅😅
God of concept 🙂
Thankyou very much sir❤
*So exited for 1M subscribers sir*
Sir lecture se start me smile hoti he aur lecture ke last me smile gayab ho jate he
It's my reality
In 12hr from 2.30M to 2.31M
Power of Physics wallah
Sir because of you my concept become clear
Sir resonance frequency pe lecture baki hai pls upload it
It will help a lot.
As it an important topic as per jee point of view 🙏🙏
Sir bahut easy lecture tha thx.. for your support
Thank you sir with all my heart
I watched all your lecture on waves and they are just amazing
Too easy to understand
However i watched it in 2x
Thank you very much
That iit 2006 question can also be solved by calculating torque net either at B or D.
Thank you so much sir...i was going in depression because you was not
telling according to my course (from pakistan)..and there is not any good content of education channel which i prepare in lockdown... but there are few topics like wave matching with my course..I
am really weak in that topic..thank you so much sir....love from pakistan❤💕💓🥰
From last question the equation is y=0.01sin(62.8/m x) cos(628/s t)
If we compare with y=Asinkx coswt. Then W=628/s but w=2πf then from this then f should be 100hz but not why???
Someone explain
Woh first fundamental frequency/1st harmonic Hain jiske liye 1/2l√T/√u use karte Hain,,tum normal frequency kii baat Kar Rahe hoo joo nhi pucha tha
Sir pllzzz Beats and Dopler Effect pr jldi sa video dalo...
Abi time hai
Love yousir for this masterpiece teaching....❤️ 💫 💫 ❣️
